Question about Plantronics .Audio 340 Headset

1 Answer

Echo problems I've been having problems with this headset, it worked fine until a few days ago. When i plug in my headset i can hear and talk, but i get a very load delayed echo that repeats several times. I have searched the plantronics website and have found nothing useful at all, and would appreciate some help. I have done the following 1 tried both mic in ports on the front and back of my pc 2 changed the volume 3 changed the voice playback/recording type 4 Made sure nothing was muted just in case =] 5 used the "test hardware" feature under the voice tab, when i use this I can get through the microphone test with everything working fine (at least it seems like it is) but when i get to the speaker test and say something it is repeated a second later Much louder and it keeps repeating.

    I am having the same issue with the plantronics audio 350 headset.

    It sounds like I'm a huge room without any furniture. It echos really badly. I believe I have everything set correctly.

    Has anyone else come across this and fixed it yet?

Check that the MIC is muted in the volume control but not in the recording settings. This could just be feedback.

My xbox 360 mic is acting up. I can talk to people but I can only hear them if the plug is twisted to a certain position

Sounds like a wire broke inside. That's why it only works when you have it in a certain position. Unless you are good at splicing wires, move the wire till you get it to work, and wrap it in that position, then don't move it at all. Good Luck.

Hey. Trying to use my Nokia wh-102 headset for my laptop, but somewhy the sound doesnt work. there is some kind of a echo... But i've found out that if i press the button attached to it, it works...

don't push that 3.5mm plug entirly into laptop's jack and i think i would work :)
i mean adjust the plug until you hear clearer sound without pressing that remotes button

There is an Echo @ the other end when I am talikng with them. It sounds fine @ my end but always a problem At the recieving end????

I just figured this out for mine - unfortunately it's a little bit of a bummer -

Experiment with your volume levels. Get a guinea pig/friend to listen for the echo while they talk - start with your listening volume all the way down while they talk, and gradually turn the volume up, until they hear an echo. Knock it back down one more notch and you should be good.

I cant talk or hear anyone talk on headset i could until about 8 days ago

This is probebly just a faulty headset, my son seems to get through 3 or 4 sets a year,In your post you have not mentioned anything you have tried, so have you tried a different headset to see if that works?
comment if you need further assistance.

When its on, i can hear what other people are saying, but they cant hear me talk

Well, this happened to me before, it wouldn't let me talk to them and I could only hear them. The problem is the cord, you have to go out and buy a new one I'm afraid. If it is new though, then it is defective.

My headphones work, my mic does not(at all)

Have you gone to your control panel, and found the "speech recognition" option? If you havent tried it, do that. It wil have you recite a sentence and then should conifgure your mic to your computer. I hope this helps!

I can barely be heard.

May not be your headset as the problem. Check you pc for mic level or plug another mic into it. If you have found this helpful or fixya, please post as such. For more help please go live

H700 Echo Problem.

Each party needs to keep their earpiece (listening) volume at the minimum level that is audible to reduce chance of feedback. Also, look to see if there is an encryption on/off option on the phone...this could be causing an echo in either state due to interference...try switching encryption on/off. Also, check your update options on the phone, you didn't say which kind of phone it is but some can get firmware updates that may be needed for bluetooth to work well. Finally, you may get results by deleting the device on the phone and re-adding it thru discovery.
